LUN reached a thin provisioning warning

[vindi-799]

I continue to get this error on my Xenservers on a newly provsioned 500GB LUN. I have thin provisioning enabled and have checked the VAAI option. I've tried setting it to 5%, 95% and leaving it blank, I still get the error. Running 11.2 U4.1

There's plenty of free space, I have 2 volume groups and it does this for LUNs on both of them.

What is the exact error?

Also, what is the output of zfs list within code tags?

 

[vindi-799]

xen2 kernel: [306751.050232] sd 1:0:0:1: Warning! Received an indication that the LUN reached a thin provisioning soft threshold.

LUNS are VG2/XENSERVER(LUN 1) and VG1/XENSERVER_VG1(LUN 10).

[dlavigne]

Were you able to resolve this? If not, does the warning persist if you update to 11.2-U5?

 

[vindi-799]

I rebooted all my hosts and freenas and haven't seen the error in a few days.

I rebooted all my hosts and freenas and haven't seen the error in a few days.

I'm struggling with the same problem with Truenas 12.0-U6. The Initiator is a Xen guest on Debian Jessie.
Did you figured out what the problem was, respectively can you show us your relevant "block shares" setting in Truenas?
